COMBINED HARROW AND DRAG.

Specification of Letters Patent.

Patented May 14:, 1912.

To all whom it may concern Be it known that I, THOMAS J. WVHEELER,citizen of the United States, residing at Lewisville, in the county ofLafayette and State of Arkansas, have invented certain new and usefulImprovements in Combined Harrows and Drags, of which the following is aspecification.

This invention has relation to harrows, and has for its object toprovide means for connecting a drag with the teeth of the harrow.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and accomaanyindrawin s in which:

Figure 1 is a perspective View of the har row showing the means forconnecting a drag to the same; Fig. 2 is a vertical sectional view ofthe same, showing the pivot pin or tooth reversed so as to permit theharrow teeth to straddle a row; Fig. 3 is a detail perspective view ofthe transverse connecting bar detached; Fig. 4 is a detail perspectiveview, illustrating a modified form of harrow tooth; Fig. 5 is a similarview, illustrating a further modification; Fig. 6 is a side elevation,partly in section of one of the harrow teeth, showing the means forattaching a board when the harrow is used as a drag.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

The harrow forming the subject matter of the present invention comprisesside bars 5 and 6, preferably formed of flat metal and having theirforward ends pivotally connected at 7. The pivoted end of the bar 5 isoffset at 8, while the pivoted end of the mating bar 6 is bent upwardlyand overlaps the oflset portion of the bar 5, the overlapped portions ofthe bars 5 and 6 being provided with alined perforations for thereception of the pivot pin 7.

The bars 5 and 6 are provided with spaced threaded openings for thereception of harrow teeth 9, the latter having their upper ends threadedand extended through i the openings in the side bars for engagement withsuitable clamping nuts 10. EX- tending transversely across the side bars5 and 6, is a transverse bar 11 also preferably I formed of a flat stripof metal having its opposite ends perforated at 12 and its intermediateportion twisted to produce an inclined bearing surface 13 for engagementwith the stock or standard 14 of a plow, indicated at 15, said standardhaving its upper end bifurcated to form a seat for the beam of the plow,as shown. The inclined bearing surface 18 is provided with an openingfor the reception of a bolt or similar fastening device 16 by means ofwhich the stock is rigidly secured to the transverse bar 11.

The rear end of the plow beam 17 is provided with the usual handles 18,while the forward end thereof projects longitudinally beyond the pivotedends of the side bars 5 and 6 and is provided with a clevis forattachment to a draft animal. Extending through the side bars 5 and 6and piercing the adjacent openings 12, are bolts or similar fasteningdevices 19 so that the bars 5 and 6 may be adjusted laterally withrespect to each other and clamped in different positions of adjustment.

The pivot 7 is preferably in the form of a screw, the lower end of whichis inclined or beveled to form a terminal point or tooth 21, there beinga nut 22 engaging the threads on the pin and bearing against the lowersurface of the side bar 5, as best shown in Fig. 1 of the drawings.

When the device is used as a barrow, the lower ends of the teeth 9 willbe preferably made pointed, as shown in Fig. 1. If desired however, thelower ends of the teeth may be deflected laterally to. form terminalshovels 23, as indicated in Fig. 4, or the lower ends thereof flattenedto produce rearwardly extended blades 24, as illustrated in Fig. 5. Theupper ends of the teeth shown in Figs. 1, 4 and 5 are all threaded so asto render said teeth interchangeable and thus permit the device to bereadily converted from a harrow into a cultivator and vice versa.

By extending the forward end of the beam longitudinally beyond the pivotpin 7 a good draft may be had, while by having the rear end of the beamterminate shortof the rear ends of the bars 15 and 6, the operator maywalk between said bars as the harrow is drawn over a field or otherinclosure so as to effectually guide the implement.

If it is desired to run the harrow and cultivator astride of a row, itis merely necessary to remove the pivot pin 7 and reverse the same withthe nut 22 hearing against the upper surface of the bar 5, in whichevent the pointed end of the pin will project above the harrow frame soas not to come in contact with the ground.

One of the teeth 9 on each bar 5 and 6 is provided with a transverseopening for the reception of a pin or bolt 25 having a terminal eye 26so that a board may be conveniently attached to the harrow and thedevice used as a drag.

Having thus described the invention, what is claimed as new is:

In a harrow a bar, a harrow tooth passing through the same, a boltpassing through the tooth parallel with the bar and Copies of thispatent may be obtained for five cents each, by addressing theCommissioner of Patents, Washington, D. C.
